celestia is a blockchain designed to be used purely by rollups

in theory it should allow to launch rollups with very cheap (and secure) fees

eg base could be deployed as an OP Stack rollup but post data to celestia instead of ethereum

closes competitors are EigenDA / Polygon Avail / ETH after 4844 (none is live yet)

What's the most successful roll up using Celestia?

Do people consider Celestia an Ethereum competitor?

Is Celestia POS? How decentralized / secure? Is it EVM or something else?

good questions

1. none, celestia launched a month ago but i haven't heard of anything deployed on it yet

2. its confusing i guess it is an eth competitor but celestia people really like eth and pretend like its not?

3. no evm, no smart contracts, just blob data for rollups.

Can be considered a competitor in data availability only post EIP-4844

Not in settlement since no contracts

It's written with CosmosSDK so has "enshrined" staking and governance modules. An active set consist of 100 validators but the number can be through on-chain governance
